Bug description:
  [impact]

  when libseccomp is upgraded to 2.5.1 on all releases, the systemd
  seccomp unit tests will start failing on ppc, as
  RestrictAddressFamilies= will no longer work on that arch.

  However, the systemd.exec man page has stated that
  RestrictAddressFamiles= doesn't work on ppc since before bionic.

  [test case]

  check systemd autopkgtest on ppc, looking at the
  test_restrict_access_familes unit test

  [regression potential]

  any regression would involve the use of RestrictAddressFamilies=,
  either no longer restricting or incorrectly restricting address
  familes.

  [scope]

  this is needed for b/f/g

  this was fixed upstream by commit
  d5923e38bc0e6cf9d7620ed5f1f8606fe7fe1168 which is included in 247, so
  this is fixed in h already

  This isn't needed in x, because it doesn't include upstream commit
  469830d1426a91e0897c321fdc8ee428f0a750c1 which reworked the code to
  switch from seccomp_rule_add to seccomp_rule_add_exact, so systemd
  could handle lack of arch support itself, instead of allowing the 'not
  exact' seccomp syscall to just ignore the call due to lack of arch
  support.

  [other info]

  libseccomp will be updated to 2.5.1 in the near future so this is
  needed before that update
